JOHN ALcoRN, or MECCA, INDIANA,

'TIRE-TIGHTEN'ER.

To all whom it may concern:

Be-it known that I, Jonx ALCORN, a citizen of the United States, residing at Mecca, in the county of Parke and State of Indiana, have invented a new and useful The Tightener; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which' it appertains to make and use the same.

This invention relates to a new and useful tire tightener.

As one of the objects of the invention it is the aim to provide a device of this nature, in which various simple, etlicient, desirable and practical features of construction are involved.

Another object of the invention is the provision of a cover plate U-shaped in cross section to fit the felly, and adapted to be removed to adjust the tire tightener. This cover plate has a slight limited movement. between the nuts of the bolts, which hold the tire to the felly, one or the other of which nuts and the corresponding bolt is adapted to be removed, in order that the cover plate may be removed.

In the drawings there is disclosed certain features, but in practical fields thesefea;

tures may necessitate alterations, to which the patentee is entitled, provided the alterations are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings, and claimed.

In the drawings :*Figure 1 is a view in side elevation showing the improved tire tightener constructed in accordance with the invention. Fig. 2. is a central longitudinal sectional view. Fig. 3 is a cross sectional view. Fig.4 is a detail view of the cover plate. Fig. 5 is a detail view of one of the angled members, to which the cover plate isslidably connected. Fig. 6 is a central longitudinal sectional' view showing the cover plate connected to the felly in a differentmanner.

Referring more particularly to the drawings 1 and '2 designate the two ends of the felly, while 3 denotes the tire, which is fastened to the folly by the bolts 4 and 5 having nuts 6. The bolts 4 and 5 also pass through the horizontal portions 7 of the angled members 8 and 9. The openings Specification of Letters Patent. Application tiled July 13,1912.

10 ofthe through which the bolts pass .are elongated. so i that when the felly spreader 12 is operated by a key 13 shown in dotted lines, the ends of the folly will move relative to the bolt. The horizontal portions 7 are provided with slots 7, which register with the openings 10 of'the felly,

sothat the horizontal portion '7 may move):

relative to the bolts. The key 13 is adapted to extend through an aperture 1% of the enlargement 15 of the spreader, so that the spreadennmy be slightly rotated. Projectmg from each side 'of the enlargement ofthe spreader IS a shank 16. These shanks are provided with right and left screw threads, so that wh n the spreader is r0- iiie felly will be' sepa rated. The shanks 6 are threaded into the vertical portions of the angled members.

The side edges of the vertical portions of the angled members are provided with slight recesses 18, which receive ribs 19 upon the inner face of the Usshaped slide plate, in order to hold the cover plate in position. However, before one or the other of the bolts 4 and 5 is arranged in position, the cover plate 20 isv disposed so its ribs will be received by the recesses 18, and after the cover plate has been properly positioned the second bolt of the bolts-4 and is disposed in place, and its respective nutthreaded thereon. The cover plate, as will be,{ iscerned, is allowed play between the nuts of the bolts at and 5. To remove the cover plate, one or the other of the bolts 4 an 5, and its respective nut is removed, after which the plate may be withdrawn. However, in Fig. G-the recesses 18 and the ribs 19 are omitted.

' rom the foregoing it will be noted there has been devised a simple and efiicient tire t i' ghtener, practical.

The invention having been set forth, what claimed as new and useful'is( In combination, a fe'lly having its adjacent ends separated, a tire on the folly, angled members disposed against the adjacent ends of the felly, the flly having elongated openings,'holts passing through the tire. the openings of thefelly and the angled members, a' device having right and left threaded shanks threaded in the angled members and adapted to be rotated to separate the adjacent ends of the felly, a U-shaped cover plate fitting the telly to and one whichhas been found shield the angled members and provided name to this specification in the presence of with ribs upon the inner side faces thereof, two subscribing witnesses. the angled members having their side edges provided with recesses to receive the ribs, I JOHx Ari/ORB 5 the U-shaped cover plate having limited \Vitnesses: Z

play between the nuts of the bolts. OLIVER HIxoN,

In testimony whereof. I have signed my A. H. BRADFIELD.
